Resource exhaustion in pypdf before 6.15.0 enables denial of service via crafted PDF files containing CID font width entries with maliciously large range values. Any application that processes untrusted PDFs using pypdf's text extraction or font parsing routines is affected, as the library iterates over attacker-controlled CID width ranges without bounds enforcement, consuming excessive CPU and memory. No public exploit code has been identified at time of analysis, and this vulnerability is not listed in the CISA KEV catalog.
CPU exhaustion in Bouncy Castle for Java's MLS (Messaging Layer Security) implementation allows a network attacker to trigger unbounded HKDF key-derivation iterations by supplying a crafted 32-bit generation counter in an MLS message. The hash-ratchet in GroupKeySet.get(int generation) advances one HKDF step per skipped generation without any upper bound, so a maximally crafted counter forces up to ~4.29 billion derivation steps on the receiving process. Scored CVSS 4.0 at 8.7 with High availability impact and no authentication prerequisites per vendor scoring; no public exploit code or KEV listing has been identified at time of analysis.
Denial of service in Next.js App Router with Server Actions allows remote attackers to exhaust CPU resources and block request processing. Affected versions include all 13.0.0–15.5.20 and 16.0.0–16.2.10 releases. No active exploitation or public exploit code has been identified at time of analysis.
Denial-of-service via algorithmic complexity in pypdf before 6.12.0 allows an attacker who can supply a crafted PDF file to cause excessive processing time during cross-reference stream parsing. The vulnerability is triggered by crafting a PDF with /W [0 0 0] field values in a cross-reference stream combined with a large /Size value, which causes the library to perform unbounded iteration over zero-byte entries. No public exploit code has been identified at time of analysis, and this vulnerability is not listed in the CISA KEV catalog; however, any application that processes untrusted PDF input using pypdf is exposed.
Denial of service via algorithmic complexity in pypdf versions prior to 6.10.2 allows local attackers to cause long runtimes by crafting a PDF with an excessively large trailer /Size value when loaded in incremental mode. The vulnerability requires user interaction to load the malicious PDF and results in availability degradation rather than data compromise. Patch version 6.10.2 is available from the vendor.
Denial of service in pypdf prior to version 6.10.1 allows remote attackers to craft malicious PDF files with oversized cross-reference stream `/Size` values or object stream `/N` values, causing excessive processing time and long runtimes. No authentication is required; the vulnerability is triggered by parsing a specially crafted PDF file. Patch version 6.10.1 is available from the vendor.
Resource exhaustion in pypdf versions prior to 6.7.1 occurs when processing maliciously crafted PDF files with manipulated /ToUnicode font entries, causing excessive memory consumption and processing delays during text extraction operations. A local attacker with file access can exploit this to degrade system performance, though no code execution or data compromise is possible. The vulnerability affects Python environments using pypdf and is remedied by upgrading to version 6.7.1 or later.
CVE-2025-55181 is a security vulnerability (CVSS 5.3). Remediation should follow standard vulnerability management procedures. Vendor patch is available.
Finance.js v4.1.0 contains a Denial of Service (DoS) vulnerability via the IRR function’s depth parameter. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.
In Genivia gSOAP with a specific configuration an unauthenticated remote attacker can generate a high CPU load when forcing to parse an XML having duplicate ID attributes which can lead to a DoS. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.
